predict is a generic function for predictions from the results of
various model fitting functions. The function invokes particular
methods which depend on the
the first argument.
a model object for which prediction is desired.
additional arguments affecting the predictions produced.
Most prediction methods which are similar to those for linear models
have an argument
newdata specifying the first place to look for
explanatory variables to be used for prediction. Some considerable
attempts are made to match up the columns in
newdata to those
used for fitting, for example that they are of comparable types and
that any factors have the same level set in the same order (or can be
transformed to be so).
Time series prediction methods in package stats have an argument
n.ahead specifying how many time steps ahead to predict.
Many methods have a logical argument
se.fit saying if standard
errors are to returned.
The form of the value returned by
predict depends on the
class of its argument. See the documentation of the
particular methods for details of what is produced by that method.
